连云港市2004～2009年流行性脑脊髓膜炎监测结果分析

目的了解连云港市流脑流行特点。方法对流脑疫情资料进行统计,采用Excel进行分析。结果全市流脑报告发病率自2004年的0.513/10万(最高值)下降至2009年的0.0204/10万,发病率呈逐年波动下降趋势。全市2004～2009年1～4月发生的流脑占总病例数的75%,发病年龄集中在0～19岁之间,占总例数的92.31%,尤以10～14岁较多,占比44.23%,发病职业分布中以学生占比最多(67.31%),正常人群流脑免疫水平监测A群、C群阳性率分别为57.24%、63.16%。结论该市流脑发病率呈逐年波动下降趋势,此现象与该市流脑疫苗接种率的不断提高及流脑疫情监测敏感性的增强有关。15岁以上正常人群中C群流脑的隐性感染率高,加强易感人群的A+C群流脑疫苗的接种已不容忽视。
